Tools you need when purchasing your Aquarium lighting

Just to share with you guys something, a handy tool when you purchase your aquarium lighting. Download any lux meter from playstore or appstore to your phone. What you need to do is position your phone 12" or 24" facing your current lighting, measure the light intensity. Screenshot the result and you can go ahead to compare the light intensity with the new lighting at your LFS. Make sure to use the same distance and take note of the surrounding ambient lighting so as to not give you a false result.

Plenty to choose from

With this tool you can now estimate if the new light will be more powerful or less powerful according to the lux meter. I've tried a few apps and they are all similarly accurate in measuring the light intensity. It is a simple tool that make life much easier instead of judging your light from the wattage shown or with your eyes which is 99% inaccurate unless you are an old timer photographer. During my photographing days we do not have digital, we were shooting film and slide and lux meter was one of the tool we had in the bag. Overtime we get to fairly accurate when reading the ambient light. .

screenshot your reading to compare to the new lighting.

BTW after using this app you will notice that wattage are a poor way to judge the intensity of light produce.

cheers

Channa Diplogramma

The Fish that started it all. (April 2014) I would like to share a story, the beginning of my fish keeping hobby that eventually got stuck with me from childhood till today. This is about a fish that had been hiding away from me for the past 30 odd years. This was the fish that inspired it all. When I was around 9 yrs old, my dad took us for a holiday trip to Singapore, we visited the Singapore Aquarium if I remember correctly. And in one of the tank on display I could not help but was instantly mesmerized by the blue fish, the body of the fish is painted in shocking blue color. I remembered clearly written on the side Toman - Channa Micropeltes because this was the first time I was introduced to the scientific names of fishes. After returning from the trip my crave for snakehead developed, I got a few snakeheads but never in blue. I asked around but nobody had ever seen or even heard of the blue Toman. I bought micros from fish shop and grow them till adult and to my disappointm...

Marulioides Care Part 1 (Bunga)

I've been reluctant to write this but many had asked me to post how to take care of marulioides for maximum performance. The truth is you need to abused it, hence Marulioides care isn't exactly the correct terms to use. Channa Marulioides is found in most part of malaysia, lakes, pond, streams, rivers, but one thing most fisherman realized are those caught in swamp, I mean really dead stagnant peat swamp. Waters that are near black in color most time the fish had tremendous performance, beautiful colors and a lot of flowers. From this theory many tried replicating the conditions with low ph and so on. I've experiment many ways of keeping marulioides and I can concur to this, Low PH meaning Ph5 and below, I usually keeps mine ard PH4 or maybe lower, because my test kit can only measure till 4 and cant read anything lower. Low PH produce beautiful coloration. As for the bunga, yes everybody wants to know this, there is no tricks, just lots and lots of experiment. It i...

Understanding Indonesian Marulioides Variant

I would like to introduce you to some of the beautiful Channa Marulioides from Indonesia and at the same time clarify the complexity and the confusion as best I can. what is Marsum, Marbor, kalimantan, borneo, sp borneo, No.1 Marsum - Marulioides Sumatera Blue Marulioides not to be confuse with Channa Melanoptera Channa Marulioides Sumatera variant is very similar to the Malaysian variant. There is also another var found there known as Blue Maru which is greyish blue in color. No.2 Marbor - Marulioides Borneo known in Indonesia or Marulioides Kalimantan or Kali by Malaysian and Singaporean. The double line The 999/eee The yy + double line Now Kalimantan is very complex and has many variant. They comes in the 2 line bands form, the 999/eee form, the YY + double line form. But one of the key factors to tell them apart from sumatera, malaysia and thai variant is the middle exposure. The key to ID kalimantan is t...
